2004 results Godfrey (30,615) stormed over former Harris-era cabinet minister David Turnbull (14,495).

2004 results Long-time Grit incumbent Jean Augustine (24,909) outdistanced Capobianco (15,159).

Hot buttons Gun violence - among the hardest-hit areas in the city. Voter turnout - the lowest in the country.

Riding breakdown Population: 106,560; total visible minority: 28,070; total immigrant: 44,745; average annual household income: $61,591.

2004 results Karygiannis (26,400) in a landslide over Tory pretender Andrew Faust (8,649).

2004 results McKay (20,950) coasted to victory over Tory Tom Varesh (8,277).
Hot buttons Crime. Political baggage Browes is carrying.

Riding breakdowns Population: 115,430; total visible minority: 97,400; total immigrant: 76,890; average annual household income: $65,929.
Main challengers Grit Derek Lee against Tory small businessman Jerry Bance.
2004 results Another Grit landslide - Lee (22,564) over independent Raymond Cho (6,962), with Tory Tony Backhurst a close third (5,184).
Hot buttons Gun crime, particularly in Malvern area. Immigration. Chinese head tax. (Chinese Canadians make up riding's largest voting bloc).
X-factors No strong independent running this time. Air India investigation - South Asians make up one-quarter of the area's voters. Tories are running Punjab-born Bance.

Riding breakdown Population: 112,370; total visible minority: 24,470; total immigrant: 40,760; average annual household income: $92,267.
Main challengers Grit incumbent Carolyn Bennett up against Tory Peter Kent and NDPer Paul Summerville.

Hot buttons Health care. New deal for cities. Libs' voting record on Israel at the UN.

2004 results Layton (22,198) in a close one over long-time Liberal incumbent Dennis Mills (19,803).
Hot buttons Waterfront. Libs parachuting in Coyne, who doesn't even live in the city, let alone the riding. Grumbling that Layton's campaigning nationally is keeping him out of the riding.
X-factors Coyne has Mills's machine. Greens' Harris moving over to run next door in Beaches-East York. Layton's immense popularity - especially among Chinese-Canadian voters, who make up largest visible-minority voting bloc here - and the fact that party leaders seldom lose.
Riding breakdown Population: 106,085; total visible minority: 36,805; total immigrant: 46,620; average annual household income: $69,834.

X-factors Health care (area boasts highest percentage of seniors of any riding in the city). Jewish-Italian split in the riding that usually votes Liberal. Dryden's star power. The odd company Mostyn keeps with pro-U.S. and Israeli-government groups. Liberal fatigue.
Riding breakdown Population: 114,530; total visible minority: 54,005; total immigrant: 61,085; average annual household income: $47,386.
Main challengers Grit incumbent Alan Tonks versus NDP's Paul Ferreira.

Hot buttons Crime. Immigration. Proposed Union Station-Pearson Airport rail link. New deal for cities. Housing.
X-factors Riding's NDP roots go back to Donald McDonald, Bob Rae, all the way to the CCF. Black vote - they make up the largest visible minority (20,055) but usually don't vote. Tonks's Tory friends, 30-year history in the area and lacklustre performance in Ottawa.
Riding breakdown Population: 110,385; total visible minority: 69,130; total immigrant: 67,360; average annual household income: $47,532.
